Automation Controller Communications

Introduction

This chapter describes and gives examples of how each type of EtherNet 
messaging, I/O messaging and Explicit messaging, is used. 

Ethernet Messaging

The Ethernet/IP Communications Auxilliary supports two types of EtherNet 
messaging. 

•

I/O Messaging — Used for deterninistic EtherNet communications with 
ControlLogix™, CompactLogix™, SoftLogix™, and EtherNet/IP scanners. 
Its primary use is to read and write I/O data for control purposes. 

•

Logic Explicit Messaging — Used for non-deterministic communications 
in which the data is not critical for control. Logic explicit messages have a 
lower priority compared to I/O messages and are used to read and write 
non-critical data. 

I/O Messaging

RS Logix 5000™ software is used to configure I/O messaging between an 
automation controller and an Ethernet/IP Communications Auxilliary on an 
Ethernet/IP network. 

The following example provides the steps necessary to configure a Logix 
controller for I/O messaging. 

ControlLogix Generic Configuration with Add-On Profiles

An Add-On Profile is available for the EtherNet/IP Communications Auxilliary 
and can be used with RSLogix 5000 version 17 and higher. The profile can be 
downloaded from:

http://suppurt.rockwellautomation.com/controlflas/LogixProfiler.asp

An existing project can be used or a new project can be created to configure 
EtherNet/IP I/O Messaging. To create a new project, perform the following 
steps.
